House hacking: Setting a budget

[Charles Mitchell]

Hey BP!

So, I'm planning on buying my first house hack within the coming months. I'd like to get some input around some budgeting questions I have. So I'm looking into some homes (all 2 familes) and I feel extremely comfortable paying $2200 a month toward my mortgage P&I taxes MIP. That places my buying power right around 500k. I can swing up to 3k but thats starting to push the budget and I would start to feel it more. However, the other side in the 2 family (3 bed 2 bath) should rent anywhere between 1800-2100. How much weight should I give the other unit when factoring my budget? Obviously vacancies happen, but I cant see properties sitting vacant very long in the area I'm looking to buy. The unit that will be rented out will be rent ready from the day of purchase.

Thanks to everyone in advance!
